Troubleshooting
Action
System event logging has stopped and a iLO MP malfunction is assumed
(system health is steady green, and power is steady green).
1. Examine console messages for any UEFI errors or warnings about iLO
operation or communications.
2. Test the operation of the iLO MP by toggling the UID locator switch
LED on the front panel -- the blue LED is turned on/off by the iLO, when
this switch is toggled.
3. Reset iLO 3 MP, by using the iLO 3 physical presence pinhole button
on the rear panel of the server.
The preceding issue is fixed when the SEL resumes logging.
Front panel LEDs indicate that the server power is turned on, and it is
either booting or running the OS (system health is steady green, and
power is steady green). Nothing might be logged for this condition.
1. Use the iLO 3 MP Command Menu to initiate a ToC, using the tc
command.
2. Reboot the OS and escalate.
3. Obtain the system hardware status dump for root cause analysis.
4. Examine the iLO 3 MP logs for entries related to processors, processor
power modules (PPMs), shared memory, and core I/O devices (see
and reading error logs" (page 73)
The preceding issue is fixed when the root cause has been determined.
Front panel LEDs indicate that the server detected a fatal error that it
cannot recover from through OS recovery routines (system health is
flashing red, SEL is red, and power is steady green).
1. Capture the MCA dump with the UEFI errdump mca command. If
the system can boot the OS, you can capture binary MCA dump files
online.
2. Examine the iLO 3 MP logs for entries related to processors, processor
power modules (PPMs), shared memory, and core I/O devices (see
and reading error logs" (page 73)
The preceding issue is fixed when the MCA does not repeat, or the source
of the MCA has been determined and dealt with.
Front panel LEDs indicate that the server detected a fatal, front side bus
error, caused by DIMMs; or by any parity in the I/O path between SBA,
LBA, or HBA (system health is flashing red, SEL is red, power is steady
green). System firmware is running to gather and log all error data for
this MCA event.
1. Examine the iLO 3 MP logs for entries related to processors, processor
power modules (PPMs), shared memory, and core I/O devices (See
"Errors and reading error logs" (page 73)
The preceding issue is fixed when the MCA does not repeat.
